DETAILED DESCRIPTION OF THE INVENTION

The following is clearly and completely describes of the technicalsolutions in the embodiments of the present invention. Apparently, thedescribed embodiments are merely some but not all embodiments of thepresent invention. All other embodiments obtained by a person who isskilled in the art based on the embodiments of the present inventionwithout creative efforts shall fall within the protection scope of thepresent invention.

Referring to FIGS. 1-5, embodiments of the present invention are set outas the following:

A vertical-shaft sewage pump with anti-collision switch includes a waterpump driving component 1, a switch control component 2, a base 3 and apost 4 fixed on the base 3, the water pump driving assembly 1 includes adriving motor 11 and a casing 12 sleeved on the outside of the drivingmotor 11, an upper end cover 13 and a lower end cover 14 whichrespectively fixed at the upper end and the lower ends of the casing 12.A plurality of cylindrical bosses 5 is disposed on the lower surface ofthe lower end cover 14. The cylindrical bosses 5 are provided withinternal threads. Screws 20 are provided at the corresponding positionsof the upper surface of the switch box 21, and the switch controlassembly 2 is installed to the lower side of the water pump driveassembly 1 via the screws 20 engaged with the internal threads providedon the cylindrical bosses 5. The switch control assembly 2 also includesa micro switch 22 housed inside the switch box 21, a guide rod 23 and afloating ball 24 which is movable up and down along the guide rod 23. Amagnetic portion is provided at an end of the guide rod 23 thatprotrudes into one end of the switch box 21. The upper and lower sidesof the floating ball on the guide rod 23 are respectively provided withan upper position limitation ring 25 and a lower position limitationring 26. An electrical connection part 6 is disposed between the waterpump drive assembly 1 and the switch controlling component 2. Theelectrical connection part 6 includes a tab 61 which electricallyconnected with the drive motor 11, a base 62 disposed on the uppersurface of the switch box 21 and a pin 63 inserting in the base 62, theupper end of the pin 63 is connected with the tap 61, and the lower endis connected with the micro switch 22 in the water pump driving assemblyvia a wire.

Further, a convex plate 7 is outwardly extended from the upper surfaceof the upper end cover 13, a circular hole is provided on the convexplate 7, and the circular hole is penetrated with a hand ring 8. Thehandle ring 8 is not limited to a circle shape, a triangle shaped ring,or a square shaped ring, which is convenient for putting on and takingoff during transportation and carrying are also applicable.

Further, the bracket assembly 9 includes a front bracket 91 and a rearbracket 92. The front bracket 91 and the rear bracket 92 are connectedby screws at one ends, and the other ends of them are pivotallyconnected via a round pin extended in a through hole. To gain ananti-slip effort, the inner surface of the front bracket 91 and the rearbracket 92 is vertically provided with non-slip guiding grooves 93. Aring-shaped fixation ring 94 disposed on the end of the rear bracket 92which is distant from the pillar 4. And the guide rod 23 is insertedinto the fixation ring 94 and plays a fixation and supporting roletherein.

During operation, when the water level rises and the float ball movesupwards, when the water reaches the upper water level, the float balltouches the upper limitation position circle and brings the guide rod tomove upwards. The micro switch in the switch box is triggered to drivethe motor to rotate and the water pump starts to work. When the waterdrops, the float ball moves downwards. When the water reaches the lowerwater level, the float ball touches the lower limitation circle andbrings the guide rod to move upwards. The micro switch resets, the motorstops rotating, and the water pump stops working.

In summary, the vertical-shaft sewage pump with anti-collision switch ofthe present invention has a simple mechanism structure and it is easy tooperate. The switch part and the pump body are integrally packaged, andthe switch and the motor are connected in the form of pin-inserting, andthe assembly structure is simplified. The integral structure is not easyto damage during transportation and has a wide application prospect.
